Synchronization TCLKA Not supported.
Synchronization TCLKB The AMC can drive synchronization TCLKB to the CLK3 clock selection circuitry on the CPM.
Synchronization TCLKC Not supported.
Synchronization TCLKD The AMC can drive synchronization TCLKD to the CLK3 clock selection circuitry on the CPM.
Fabric FCLKA Fabric FCLKA is driven to the AMC bay by the 100-MHz PCIe clock generator on the CPM.
Common option Fabric ports 0 and 1 Ports 0 and 1 of the AMC bay connect 1000Base-BX Ethernet to the Fabric multiplexer on the CPM.
Common option Fabric ports 2 and 3 Ports 2 connects to the SAS multiplexer. The Port 2 connection switches between SAS channel 0
from the RTM and SATA channel 0 from the ICH. The Port 3 connection passes directly to SAS
channel 1 on the RTM. These interconnections are compliant with the PICMG AMC.3 Storage AMC
specification.
Fat Pipes Fabric ports 4, 5, 6, and 7 Ports 4 through 7 of the AMC bay connect to IOH PCIe port 9 on CPM with a x4 link. These
interconnections are compliant with the PICMG AMC.1 PCI Express AMC specification (Type 4).
Fat Pipes Fabric ports 8 and 9 Ports 8 and 9 of the AMC bay connect 1000Base-BX Ethernet to the Fabric multiplexer on the CPM.
Fat Pipes Fabric ports 10 and 11 Ports 10 and 11 are unused on CPM.
Extended options Fabric port 12 Port 12 of the AMC bay is connected to the update channel through the equalizer, and allows up to
3.2 Gbps throughput (spare SAS multiplexer ports are used for this task). This provides direct
interconnection between AMC modules on redundant CPM carrier blades.
The E-Keying function is provided by the IPMC, which controls the enabling over an I
2
C bus.
Extended options Fabric port 13 Port 13 of the AMC bay is dedicated to a non-standard “slow path” update channel. The connection
is used for single-ended general-purpose I/O (GPIO) signals.
The E-Keying function is provided by the IPMC on the CPM, which controls the enable pins of the
buffers using GPOs. The signals on Port 13 are non-LVDS, and therefore must power up disabled
until E-keying enables them.
Extended options Fabric port 14 Port 14 is unused on CPM.
